Can anyone please recommend a good free graph plotter that I can download. I am looking for a program that can produce neat looking graphs with all the axes, grids and that can plot many different functions. I tried to use Geogebra but I don't really like because the results of the plot look less like those found in most textbooks (Geogebra has different font, etc). I also used MathLab and Mathematica but I don't think those are beautiful enough to be displayed in textbooks or articles.

I tried to download "Graph" https://www.padowan.dk/download/, but the exe file is always corrupted so I cannot install.

And if possible I want the graph to be converted and saved as picture formats like JPEG, PNG, and also PDF etc.

Thanks for the recommendation.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

If you're looking for something programmatic you could give gnuplot a go, there are also a bunch of libraries so you can use it via different programming languages. If you're writing a document with LaTex (or some other tex variant) you could also use tikz I believe.

If you're using a Mac, try Grapher, which comes with the system.

If you can use an online program, make sure to try Desmos.

xmgrace is pretty good though I prefer gnuplot.
